R 删除向量中包含包含特定字母的字符的位置

我有vector asset.name\u vct，其中包含以下字符

 [1] "A3TV"    "ABE"     "ABG"     "ABG.P_0" "ABG.P_1" "ACS"     "ACX"     "ACX_0"  
 [9] "AENA"    "AGS"     "ALT"     "AMS"     "ANA"     "ANA_0"   "BBVA"    "BKIA"   
[17] "BKIA_0"  "BKT"     "BME"     "BTO_0"   "BTO_1"   "CABK"    "CAR"     "CIE"    
[25] "CIN"     "CLNX"    "COL"     "COL_0"   "CRI"     "DIA"     "EBRO_0"  "EBRO_1" 
[33] "ELE"     "ELE_0"   "ENC"     "ENG"     "EVA"     "FAD"     "FCC"     "FER"

[49] "LOR"     "MAP"     "MAP_0"   "MAS"     "MEL"     "MRL"     "MTS"     "NHH_0"  
[57] "NHH_1"   "NTGY"    "OHL"     "POP"     "PRS_1"   "REE"     "REE_0"   "REP"    
[65] "SAB"     "SAN"     "SCYR_0"  "SCYR_1"  "SGC"     "SGRE"    "SGRE_0"  "TEF"    
[73] "TEM"     "TL5"     "TRE"     "UNF"     "VIS"     "VIS_0"   "ZEL"

我想删除所有包含“_”的位置

可以使用

grepl（）

创建布尔条件来过滤向量。下面是一个可复制的示例：

vec[1]“ABC”“DEF”“GHI”
